In the world of spies, double agents, and triple agents, where intelligence agents go to great lengths to conceal what they know and mislead counterintelligence operatives, it seems astonishingly brazen for Wang 'William' Liqiang to outright identify himself. Yet he not only did it, he apparently gave interviews that revealed his face (i.e. this rules out Wang 'William' Liqiang being a false name). If his claims are true, then this ought to make it easy for China not just to plug the intelligence leak (they can confirm the identity of the agent who's defecting), they can even retaliate easily against any of Wang 'William' Liqiang's family members or loved ones still in China.
It's not just Wang doing it - it seems equally brazen for Australia's security services to allow Wang to do it. The whole thing sounds fishy enough that I'm getting the feeling it's all part of a bigger conspiracy by unknown parties hoping to entice intelligence wins from the other parties.
Has there been any publicly-released information about why Wang 'William' Liqiang identified himself (+ was allowed to do so)?
